Xinrui Laboratory High-Purity Water Analysis Instruments can almost completely remove conductive media from water, as well as reduce non-dissociating colloidal substances, gases, and organic matter to very low levels. The resistivity exceeds the limit value of 10–18.3 MΩ·cm. Ultrapure water is a level that is difficult to achieve with general water purification equipment. It is typically produced using industrial high-purity water systems through four major steps: pretreatment, reverse osmosis technology, high-purity treatment, and post-treatment. Multiple filtration stages, high-performance ion exchange (polishing), ultrafiltration filters, UV lamps, TOC removal devices, and other treatment methods are employed to achieve a resistivity of up to 18.25 MΩ·cm.
Detailed Introduction
Xinrui Laboratory High-Purity Water Analysis Instruments are commonly used equipment in scientific laboratories, meeting the technical requirements for purified water in experiments.
Xinrui High-Purity Water Analysis Instruments are designed with different pretreatment functions, configured with various filtration units tailored to different water qualities, such as softening and strong activated carbon adsorption units for high hardness and high turbidity.
Small microcomputer control function: Operated by a small microcomputer, the system automatically shuts down in cases of water shortage or full water levels, and performs an automatic flushing function upon each startup.
Compared to traditional electric thermal water distillers, it produces water with higher purity and stability; it is easy to operate and does not require dedicated personnel for monitoring; it uses no electric heating tubes, preventing scaling and ensuring safety.
Features of the Xinrui Laboratory High-Purity Water Analysis Instrument System:
· Equipped with a silent pump, the system operates without vibration, noise, or electromagnetic radiation, ensuring no impact on the working environment.
· Utilizes reverse osmosis membranes with stable performance, high desalination rate, and long lifespan.
· Employs exchange resin for (ultra) purification columns, offering high exchange capacity and superior water quality.
· Features an all-metal chassis with electrostatic spray painting, effectively preventing corrosion from moisture.
· Separated water and electrical circuits avoid the impact of humid environments on electrical components.

Product Features

2. Uses imported ion filtration membranes and high-pressure, silent pure water pumps for more reliable operation and broader applicability to various water qualities.
3. Features a system flushing function: Before water production upon startup, the system automatically flushes for 18 seconds before beginning water production.
4. Includes a system protection function: The equipment automatically shuts down when water pressure is too low or there is no water, and automatically restarts when water supply resumes.
5. High output, low energy consumption, and electricity savings: Output of 20L/h with a power consumption of only 25W, which is 1/300 of similar products.
6. Employs advanced water treatment processes, with a high-purity water output ratio of about 40% and low water consumption.
7. No electric heating tubes, no scaling, and no need for cleaning.
8. No heat loss; output water is at room temperature and requires no cooling, making it directly usable for experiments.
9. Easy to operate, maintain, and low operating costs.
10. Equipped with a two-stage RO pre-desalination system (optional for high salinity water).
11. Capable of water quality and quantity upgrades. 12. The RS-II series, in addition to the features and functions of the RS series high-purity water machines, also includes water quality monitoring, enabling real-time monitoring of output water conductivity and temperature.
Why Use a High-Purity Water Machine?
· Stable water quality output, simple testing methods, no need for repeated experiments.
· High water output, with base models of 10L/H or 20L/H, up to 100L/H.
· Output water at room temperature, requires no cooling, can be used directly, reducing experiment analysis time and avoiding secondary contamination during cooling.
· On-demand water production, avoiding time wasted during transportation and speeding up analytical experiment efficiency.
· Most importantly, the instrument operates at only 25W, significantly more energy-efficient compared to electric thermal water distillers, which typically consume 7–8 kW, commonly 10 kW, or even 15 kW, reducing daily operating costs.
